Improving feature extraction, event detection, and target classification in multi-sensor systems requires new mathematical methods and processing techniques. In addition, previous research and experience suggests that leveraging sensor data that has not experienced significant dimensionality reduction can preserve subtle features when processed jointly with other relevant data. However, traditiona ...

Endpoints in the Internet of Things (IoT) vary considerably in their hardware-software architecture and their functional capability. The IoT marketplace is unlikely to converge on a single or a few dominant endpoint platforms in the near term and potentially even long term future.This creates a major problem and an opportunity for securing IoT endpoints that are being increasingly integrated in cr ...

The widespread adoption of cloud computing resources has resulted in the proliferation of virtualization technologies.New technology begets new attack vectors; consequently, a new breed of malware techniques have emerged that detect the presence of a virtual machine or hypervisor and respond by directly attacking the hypervisor in an attempt to breakout of the virtual machine container. To counter ...

Extracting information from different modalities of data is one of the greatest challenges in this era of exponential data growth, as well as one of the most promising horizons for the development of new capabilities for military, commercial, and scientific applications. Virtually all areas of defense, industry, and science are becoming increasingly dependent on the ability to analyze multimodal d ...

EO/IR sensors can provide high spatial resolution images using multiple frequency bands ranging from the visible to mid-wave IR. EO/IR sensors have been very successful for terrain imaging from subsonic aircraft and from satellites. Imaging using these platforms has been studied extensively. EO/IR sensors can provide high spatial resolution images using multiple frequency bands ranging from the v ...

Scramjet engines are designed to operate across a wide Mach number range and typically incorporate isolator sections to provide sufficient back-pressure margin and prevent unstart. As military requirements become increasingly demanding, an active, closed-loop control system is necessary to maintain engine stability and power output. During Phase I, key components of a scramjet control system were ...

The goal of the proposed work is to demonstrate 100 kHz to MHz rate nonlinear spectroscopy for measurements of molecular energy distributions, energy transfer, major species, and temperature in transient combusting and nonequilibrium flows. This will be accomplished, in part, by extending burst-mode laser technology to the fs/ps regime for three-orders of magnitude higher probe-pulse energy at MHz ...

The US Air Force requires quantitative spatially and temporally resolved measurements of key rate-controlling intermediate species in reacting flows at elevated pressures for Air Force advanced propulsion systems. Such information is critically needed fo...

The Phase-I effort is to demonstrate high-speed, polarization-based, burst-mode-laser-enabled, dual-plane, stereoscopic PIV (DP-stereo PIV) measurements of turbulent swirling combustion, which allow complete determination of the nine-component velocity g...

The objectives of this research effort (combined Phase-I and Phase-II) are to experimentally derive the scaling laws up to 30 bar for key combustion species and temperature for reactions involving various hydrocarbon fuels in such a way so that the measu...
